Ethereum currently offers quite a few entry opportunities. My approach is to do a buy low at 3190 and 3150. The previous low was around 3180, which is indeed a level worth paying attention to. Currently, the price is around 3220. If we consider the low point at 3190, there's roughly a 30-point profit margin to be made.

The key is whether it can hold above 3250. Once 3250 is effectively broken through, consider holding the position and expecting a larger upward move. But if it repeatedly encounters resistance at 3250, there's no need to be overly optimistic—treat it as a normal small wave, cut losses when needed, and don't expect to get rich overnight.

In the short term, the battle between support and resistance will continue. Patience in waiting for signals and risk control are more important than anything else.
